Abstract

The nickel(II) complex Ni(L)Py (I) (L is 1,3-bis(3,5-di-tert-butyl-2-phenolato)-5,5-dimethyl-(4,6-dihydropyrimidin-2-ylidene)) containing the dianionic bonded N-heterocyclic carbene (NHC) bis(phenolate) ligand is synthesized. In the presence of a stronger base (4-dimethylaminopyridine (DMAP)), the exchange reaction occurs with the replacement of pyridine in complex I by the DMAP molecule to form complex Ni(L)(DMAP) (II), the crystal structure of which is determined by XRD. The synthesized compounds are characterized by elemental analysis, mass spectrometry, and NMR spectroscopy. The spectral characteristics of the compounds are studied.

镍（II）与双（酚酸酯）钳形n杂环卡宾配体的配合物：合成、结构和性质

合成了镍（II）配合物Ni(L)Py (I) （L为1,3-二（3,5-二叔丁基-2-苯酚）-5,5-二甲基-（4,6-二氢嘧啶-2-乙基）），含二阴离子键合n-杂环羰基（NHC）二（苯酚）配体。在强碱（4-二甲氨基吡啶（DMAP））存在下，配合物I中的吡啶被DMAP分子取代形成配合物Ni(L)(DMAP) (II)，发生交换反应，用XRD测定了配合物Ni(L)（DMAP）的晶体结构。合成的化合物通过元素分析、质谱分析和核磁共振光谱分析进行了表征。研究了化合物的光谱特性。
